AI

Apex is now publicly available. Explore Callstack’s coding model for React Native and Next.js, with API pricing, benchmarks, and self-hosting options.

Explore Jev with Kewin Wereszczyński and Szymon Chmal: how it works, its approach to faster agent decisions, and possible local alternatives.

Explore faster, lower-cost mobile QA with Jev and agent-device. Watch the demo, see the code, and try the CLI proof of concept yourself.

Join 500+ engineers in Warsaw Sept 17-18 2026 for Agent Conf. Learn agentic development, orchestration, and AI-driven workflows.

Lech Kalinowski will show how Agents Commander lets multiple AI coding agents collaborate directly in one terminal without a central server or heavyweight framework.

Nico Martin explains how Transformers.js uses WebGPU and ONNX to run AI in the browser, plus the limits of local models and on-device agents.

How connected state, retrieval, memory, and verification carry coding agents across complex, multi-step workflows. Kewin Wereszczyński and Lech Kalinowski discuss the structures that let agents plan, retrieve context, use tools, and keep working across longer tasks.

Join us in Boston on August 18 for an evening focused on a question most teams hit quickly with AI agents: how do you make them dependable once they leave the prototype phase and start touching code, workflows, and delivery timelines?

See how Apex, Callstack's React Native model, compares with frontier models on navigation, animations, async state, and performance-heavy UI work.

See how agent-device replay cuts repeated mobile QA flows from minutes to seconds, reduces model calls, and shows when repair is worth the cost.
